Polyporus mollis (=Weinmanni). There are two species in Europe 

 that are white in their prime, but spot red on the slightest touch, and 

 turn reddish when old. One (Polyporus mollis) is a large species, dimidiate, 

 usually two or more inches in diameter, and the surface strongly tomentose, 

 strigose. The other, Polyporus fragilis, is small, and generally sub-resupi- 

 nate, with a pileus effuso-reflexed. There is no question as to what Persoon 

 called Polyporus mollis (Obs. p. 22), but I have long puzzled over what 

 distinction Fries made between the two species, both from his writings 

 and his Icones. I am forced to the conclusion that he only knew one plant 

 under both names, and that Polyporus fragilis and Polyporus mollis, in 

 the sense of Fries, were the same plant (fragilis). And what Persoon called 

 Polyporus mollis, Fries called Polyporus Weinmanni. 



Polyporus amorphus. Frequent in the pine regions of Europe, but 

 very rare in America. Stereum tuberculosum ? Merulius aureus. Poly- 

 porus dichrous, or Gleoporus, if you wish, but not "Gleoporus conchoides 

 Mont.,"' which, while often applied to this plant in American mycology, 

 should be restricted to the thin, pale, conchoid, tropical form. Polyporus 

 fragilis. Polyporus altocedronensis ? Irpex unnamed I think. Stereum 

 sanguinolentum (very?). "On Birch." 



Polyporus lucidus, typical, except this is more obese and horizontal, and 

 lucidus in the East is "auriscalpium" shape. I presume this is what has 

 been called "Ganodermus Oregonensis." Polystictus velutinus, pale and 

 smoother form than usual. Fomes annosus. Daedalea unicolor. Daldinia 

 (Sp.). Fomes carneus. Polyporus. Unknown to me. Thin, soft, conchoid, 

 white. Spores 2 x 5. Polyporus Berkeleyi. "Common at base of old 

 larches." Merulius niveus. Stereum versicolor. Irpex lacteus. Polyporus 

 (Sp.). Clavaria Ligula. Dacryomyces (Sp.). Spathularia flavida. Cudo- 

 nia circinans. Clavaria inaequalis. Polyporus alboluteus. Chlorosplenium 

 aeruginosum. Polyporus dichrous. On Cedar, a rare host. Trametes. A 

 Western species. Unknown to me. Fomes conchatus, very?? 



Polystictus versicolor, brown form very close to what Fries called 

 Polystictus zonatus. Peziza (Cochlearia) aurantia. Polyporus unknown to 

 me. Hydnum (resupinate). Polyporus adustus. Lenzites saepiaria, on 

 birch. Irpex lacteus. Merulius aureus, fine specimen. Polyporus amor- 

 phus, with reddish hymenium. In Sweden amorphus occurs with white, 

 yellow, and red hymenium. In this country in the East it is rare or absent. 



Polyporus radiatus. Merulius (Sp.). Polystictus versicolor (on Larix, 

 unusual host). Hirneola auricula-Judae. Merulius pulverulentus (=M. 

 brassicaefolius Schw.). Lentinus' lepideus. Merulius molluscus. Poly- 

 porus spumeus. Polyporus volvatus. A very large specimen, 2% inches in 



diameter. Polystictus hispida. Trametes pini. One of the collections 



(the thin one) has a more strongly zonate surface than usual. Fomes 

 laricis. Polyporus Schweinitzii. Polyporus benzoinus. Fomes pinicola. 

 Polyporus sulphureus, on hemlock. Hydnum coralloides.
